Comment 58 for bug 286285

Thank you Antonio. That helps assure me that the results I'm seeing apply to the patch. As also reported above, I now can't shutdown cleanly without hitting the wifi switch. I'm not certain whether this is a new behavior or heightened awareness of an existing issue.

for clarity's sake,

11 hours ago, I removed...
linux-backports-modules-intrepid
linux-backports-modules-intrepid-generic
linux-backports-modules-2.6.27-7-generic
...and followed that with a reboot. Then I patched and rebooted again. Then I rebooted several times and haven't seen the "scheduling" bug.

Currently synaptic shows no backports packages installed.
